External Email - Use Caution
Dear colleagues Freesurfer experts,
I would like to create an atlas (my atlas) for the white matter like "wmparc.mgz" so I can generate statistics.
I would like this atlas to be limited to the following structures (frontal lobe, parietal lobe, occipital lobe and temporal lobe). I reviewed Freesurfer tutorials and Q&A in Freesurfer forum then ran the following commands:
mri_annotation2label --subject subject --hemi lh --lobesStrict lobes
mri_annotation2label --subject subject --hemi rh --lobesStrict lobes
mri_aparc2aseg --s subject --labelwm --hypo-as-wm --rip-unknown --volmask --o wmparc.lobes.mgz --ctxseg aparc+aseg.mgz --annot lobes --base-offset 200
Then,
mris_ca-train -t ./color.tab lh ../surf/lh.sphere.reg ../label/lh.lobes.annot SUBJECT_TEST lh.my_atlas.gcs
mris_ca-train -t ./color.tab rh ../surf/rh.sphere.reg ../label/rh.lobes.annot SUBJECT_TEST rh.my_atlas.gcs
I would like to use mri_segstats with “my atlas” to generate statistics in lobes not in parcellates. How can I convert lh.my_atlas.gcs and rh.my_atlas.gcs to myatlas.mgz ?
Thanks for your help
James
